Two large metal plates X and Y are parallel to each other and are placed in a vacuum, as shown. Plates X and Y have charges that are equal in size and opposite in sign. What happens to the force on a positively charged particle as it moves from plate X to plate Y?
- AIt decreases because the positively charged particle is moving away from the positively charged plate.
- BIt decreases because the positively charged particle is moving in the direction of the electric field between the plates.
- CIt increases because the positively charged particle is moving closer to a negatively charged plate.
- DIt remains constant because the positively charged particle is in the uniform electric field between the plates.
